Working Principles

The SN74AHC573DWG4 operates as an octal transparent D-type latch with 3-state outputs. It uses high-speed CMOS technology to provide fast operation. The latch enables data inputs to pass through to the outputs when the latch enable (LE) signal is active. The output enable (OE) signal controls the state of the outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74AHC573DWG4 is commonly used in various applications, including: - Data bus buffering - Memory address register buffering - General-purpose digital logic circuits - Microcontroller interfacing
